Abstract
UF-IC-MBR process was used to treat wastewater from potato starch production,the operation parameters of IC reactor treating the said kind of wastewater were mainly studied.The results showed that,under normal temperature,when the influent COD mass concentration was 6 000-9 000 mg /L,the HRT was 5 h,the volume loading was 23.62 kg[COD] /(m3·d),the removal rate of COD by the IC reactor was 91.43%.It could be seen that,using the said process to treat wastewater from potato starch production,the quality of the effluent water could meet the reuse standard.
